Both our installations of OpenMeeting are still up and running. All
user activities appear to be successful. The only viewable problem is
that the blue default user image icon sometimes is not displayed on
the home page.
And, I am now getting the error shown below when users return to the
home page from the conference room list page. See the "Caused by:"
explanation in the 39th line below. I have verified that
autoReconnect is set to true in the connection.url property in
hibernate.cfg.xml and that I am using Connector/J 5.1.7.

testing connection validity before use in your application, increasing
the server configured values for client timeouts, or using the
Connector/J connection property 'autoReconnect=true' to avoid this
problem.
